On DC's Legends of Tomorrow, the final night of the CW's Invasion crossover week ended with Barry Allen offering to save the world, the world he messed up in the first place. But, when he tried to walk away from the rest of the heroes, so he could turn himself over to the dominators, Oliver Queen called him back.
"No offense, Oliver, but you and what army?" Barry asked, and when he turned around, all of the heroes had gathered to show their collective support for The Flash. Barry wasn't the only one questioning his purpose, the other heroes were also asking themselves if they did more harm or more good in the universe.
Fortunately, the heroes chose to do good, and in an epic fight scene against the dominators, they came together for the betterment of all humanity. Spoiler alert! The heroes win the battle, and afterward, Supergirl, Flash, and Green Arrow drink champagne and share a group hug.
